--------------
We have recently acquired many pieces of laboratory glassware.
We will be listing several additional pieces every week during the coming months.
We are not experts in identifying or understanding the uses for all of these items.
We have done our best to identify each piece, take measurements, label joints, etc.
If we have left out an important piece of information, or if we have misidentified something, please let us know.
